摘要:
A brake system, especially for a wind turbine generator, comprising a brake disc (12) is disclosed. The brake system comprises at least one flexible portion (15, 16) being configured for compensating and/or absorbing expansion of the brake disc (12).
摘要:
A system and method for collecting fluid leaking from a component of a wind turbine are disclosed. In one aspect, the system may include a flexible sheet (102) formed from a fluid resistant material. The flexible sheet may generally be supported at or adjacent to a leakage zone (104) defined below the component of the wind turbine (10).
摘要:
Die Erfindung betrifft eine Rotornabe einer Windkraftanlage. Eine Rotornabe einer Windkraftanlage beinhaltet mindestens zwei Verbindungsstellen zur Aufnahme jeweils eines Rotorblatts. Die Rotornabe ist von einer Verkleidung umgeben, wobei die Verkleidung mindestens zwei Aussparungen für jeweils ein Rotorblatt aufweist. Zwischen den zwei Verbindungsstellen zur Aufnahme der Rotorblätter ist der Abstand zwischen der Rotornabenverkleidung und der Rotornabe so gestaltet, dass zwischen Rotornabenverkleidung und Rotornabe ein Hohlraum entsteht, der groß genug ist, damit von dort aus Wartungsarbeiten an der Verbindungsstelle zwischen Rotorblatt und Rotornabe von einem Arbeiter durchführbar sind.

A bedplate assembly 30 of a wind turbine 10 is provided. The bedplate assembly 30 includes a rotor shaft 24 with a first end 25 coupled to a rotatable hub 26 of the wind turbine 10 via a rotor flange 44 and a second end 29 coupled to a gearbox 20. The bedplate assembly 30 also includes a bedplate support frame 32 coupled to the gearbox 20 and to the rotor shaft 24 for supporting the gearbox 20. The bedplate support frame 32 includes a torque arm support device 50 for supporting torque arms 52, 54 of the gearbox 20. The bedplate support frame 32 also includes a circular support 66 for housing a shaft support bearing for supporting the rotor shaft 24 at the first end 25. Further, the bedplate support frame 32 includes a cross-structure 56 located under the rotor shaft 24, wherein the cross-structure 56 comprises one or more arms connected internally to a first side wall 62 and a second side wall 64.

摘要:
The invention relates to a liquid damper in a wind turbine. A damper system of a direct driven wind turbine is disclosed, whereby the wind turbine comprises a nacelle, a rotor hub and an electric generator. The electric generator comprises a rotor and a non-rotating part. The rotor hub is connected to the rotor of the electric generator. The non-rotating part of the generator is connected to the nacelle. The wind turbine comprises a damper system to at least partially eliminate an unwanted movement of the wind turbine resulting from wind loads, whereby the damper system comprises a liquid damper. The damper system is arranged at a non-rotating part of the electric generator.
